Too Much Gain the Issue ? (preamp and amp)

I have a Cary SLP-05 preamp- 24db gain with balanced and 17db single ended.  

Using a Pass Labs XA30.8 (26db gain) and even with the 17db of the single ended output of the Cary preamp the sound can frequently be sibilant in the upper midrange.   

Have not had the sibilant sound with other amps (Parasound JC5) but did lower the gain on that amp to 50% of dial.  

Thanks.

thanks so far.

couple things-

not really a brigtness issue, more like slightly hissy treble.

my pass xa25 sounds perfectly clean

cary can adjust the gain but i am not willing to go down that road

That’s because the Voltage gain is lower, on the Pass Labs XA25 amp which is 20dB gain and the Pass Labs XA30.8 amp is 26dB gain lower, gain less hiss. 😎
